COOLING-URN.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed December 19, 1912. Serial No. 737,630.

To all whom it may concern:

Be it known that I, HENRY D. KELLY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Cooling-Urns, of which the following i a specification.

This invention relates to dispensing urns for cold milk, cream and the like, and my obj ect is to produce an urn of such construction that no sweating action can occur on its exterior surface to mar, injure or destroy the nickle or silver plating thereon.

WVith this general object in view and others as hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which Figure 1, is a central vertical section of a dispensing urn embodying my invention. Fig. 2, is a horizontal section of the urn. Fig. 3, is an enlarged central vertical section of a combined overflow, clean-out and drain.

In the said drawing, 1 indicates a shell or casing of cylindrical form and adapted to be nickel plated or silver plated and said cylindrical casing or shell is preferably mounted upon legs 2. The shell is provided near its upper end with holes 3, and in its bottom with holes 4:, the latter being preferably produced by punching upwardly so as to provide upstanding circular walls 5, which guard against any water which may gather upon the bottom of the casing flowing through said holes. Arranged concentrically within said shell or casing 1 is a cylinder 6, provided at its upper end with an outwardly projecting circular flange 7 secured in any suitable manner with a water tight joint to the shell or casing 1 above the holes 3 thereof, and said cylinder 6 is provided at its lower end a slight distance above the bottom of the shell or casing 1 with an inturned flange 8.

Arranged concentrically within cylinder 6, is a cylindrical tank 9, provided with a suitable number of sharp-pointed feet 10, which rest upon flange 8.

11 is a horizontal ring secured peripherally to the shell or casing l and projecting inwardly across the top edge of the wall of the tank and terminatlng at its inner margin in a circular flange12, which depends into the upper end of the tank but does not contact therewith.

13 is a cover for the urn provided with the customary handle 14.

15 is a drain pipe extending up through the shell or casing and the tank and provided with a centrally perforated cap 16 at its upper end. It is also provided within and near the bottom of the tank with discharge holes 17 and adjacent the bottoms of said tank and shell or casing with clean-out and drain holes 18 and 19 respectively. In the plane of'the bottom of the tank, the wall of the pipe 15 is of increased thickness and the passage through the thickened portion tapers downwardly to constitute a valve seat 20.

21 is a tubular valve extending from the valve seat 20 up through cap 16, and provided at its upper end with a handle 22 and.

at its lower end is tapered to engage seat 20 and is provided with an opening 23 to be thrown into communication with the cleanout hole 18, when the valve is properly adjusted. This tubular valve is also provided at the height it is desired to have water stand in the tank, with overflow holes 24: so that any surplus water in the tank will escape by passing through holes 17 and 24 and pass from the tubular valve through the lower part of pipe 15.

Arranged within the tank is one or more liquid receptacles 25 each provided with a cover 26, and a discharge pipe 27, each pipe 27 extending through the bottom of the tank with a liquid tight joint and communicating with the valve casing 28, extending down through the bottom of the shell or casing and connected below the latter by a pipe 29, to the drain pipe 15. The valve 30 of each casing 28 controls the passage of the casing above the point of commumcation therewith of pipe 29.

Each discharge pipe 27 is provided with a laterally extending pipe 31, connected by a pipe 32 with a faucet 33, the pipeway composed of parts 31 and 32 extending through the shell or casing 1, cylinder 6 and the wall of the tank 9. To minimize the area of contact between the pipeway and the tank Wall and shell or casing, asbestos or equivalent gaskets 34 are interposedbetween the wall of the tank and the inner portions of the pipeways and the collars 35 of the outer portions of the pipeways, and to minimize the area of contact between the receptacles 25 and the discharge pipes 27 and between the latter and the bottom of the tank 9, similar gaskets 36 are employed.

Assuming that the receptacles are charged with a liquid which it is desired to keep cold and sweet as long as possible, water and ice will be placed in the tank, the depth of the former being regulated by the height of the openings 24. As the temperature is lowered the tank will sweat and this water of condensation will drain down upon flange 8 of cylinder 6 and then flow down onto the bottom of the shell or casing and thence off through the drain hole 19.

Air circulates between the casing or shell and the cylinder 6, entering through holes 3 and as its temperature drops, descending and eventually passing out through holes 4, this circulation of air being sufficiently active to evaporate any moisture which might tend to accumulate on cylinder 6, and guarding against such change of temperature between the inner and outer surfaces of the casing or shell as would result in the production of sweat upon the exterior surface of such casing or shell, it being noticed in this connection that air cannot circulate with any facility or rapidity through the space between the tank and cylinder and hence such space insulates the tank and thereby results in an economy in the use of ice.

When it is desired to clean out the tank, the handle 22 is turned until the opening 23 in valve 21 registers with the clean out hole 18 in tube 15, and when it is desired to drain one or both of the receptacles 25, the underlying valve or valves 30 are opened to permit the liquid from receptacles 25 to flow through pipes 29 into pipe 15. For drawing off the contents of either of said receptacles, the proper faucet 33 is operated.

It will be understood of course that this urn may be equipped with gage glasses, not shown, to indicate the height of the water in the tank and the height of the milk or cream in the receptacle or receptacles 25.

It will be understood that the only points of contact between tank 9 and the casing or shell are where the tapered legs 10, engage the flange of cylinder 6 and that the area of such contact is so minute that the temperature of the casing or shell is little afiected and consequently no condensation or moisture from the atmosphere will collect on the exterior surface of the casing or shell. WVith ordinary urns of this general character the exterior surface sweats most of the time and if the urn is nickel plated or silver plated, it is necessary to replate about every three months or six months respectively, if it is desired to have the same always present an attractive appearance, as these urns are usually prominently displayed in cafeterias and the like.

From the above description, it will be apparent that I have produced a dispensing urn possessing the features of advantage enumerated as desirable, and I wish it to be understood that I reserve the right to make all changes properly falling within the principle of the invention as defined by the appended claims.

I claim 1. An urn comprising a casing or shell provided with openings at its upper and lower ends, a cylinder fitting in the casing and terminating short of the bottom and top thereof and provided at its upper end with a flange projecting outward to the casing or shell above the openings at the top thereof, a tank arranged within the cylinder and suitably supported, a receptacle within the tank, provided with a pipeway extending laterally through the tank, cylinder and shell or casing and having a branch extending downward through the bottom of the tank and shell or casing, a valve controlling the branch at a point below the tank, and a faucet mounted upon the outer end of the laterally extending portion of the pipeway.

2. An urn, comprising a casing or shell provided with openings at its upper and lower ends, a cylinder fitting in the casing and terminating short of the bottom and top thereof and provided at its upper end with a flange projecting outward to the casing or shell above the openings at the top thereof, a tank arranged within the cylinder and suitably supported, a receptacle within the tank, provided with a pipeway extending laterally through the tank, cylinder and shell or casing and having a branch extending downward through the bottom of the tank and shell or casing, a valve controlling the branch at a point below the tank, a faucet mounted upon the outer end of the laterally extending portion of the pipeway, and a drain pipe extending from the tank through the bottom of the casing or shell.
